Earlier this evening, i was bored, so i went on youtube and on my recommendation list was a video produced by a man that makes nixie tubes in the Czech Republic. I started to think about the bird neon tube used in televisors, and was wondering about the fine details. What was the cathode made of? What was the anode made of? What gas mixture was used in it? And what was the striking voltage? i know that in order to keep the anode from being in front of the glow, Baird put it behind the cathode, and put a sheet of mica in between the two to keep the glow to the front. But the most important question of all- What were the dimensions of the tube, and what were the dimensions of the cathode? i had heard of the unsuccessful attempts to make a working replica in Australia that Chris Long had helped with, and i may as well contact him. Any answers to these questions would be MUCH appreciated. I also wonder how much his prices are for tubes, especially custom ones that haven't been manufactured in 80 years!
